Hospital Ownership Conversions: Defining the Appropriate Public Oversight Role
(Forum for Health Economics & Policy, 2002-01)
This paper reviews recent empirical evidence on the effects of hospital ownership
conversions on quality of care and provision of public goods, such as uncompensated
care, and presents new results on these topics based on ...
Activation in mesolimbic and visuospatial neural circuits elicited by smoking cues: evidence from functional magnetic resonance imaging.
(Am J Psychiatry, 2002-06)
OBJECTIVE: The authors sought to increase understanding of the brain mechanisms involved
in cigarette addiction by identifying neural substrates modulated by visual smoking
cues in nicotine-deprived smokers. METHOD: Event-related ...
Smoking Cues Elicit Activation in Mesolimbic and Visuospatial Neural Circuits: Evidence from fMRI
(American Journal of Psychiatry, 2002)
Differential mechanisms of morphine antinociceptive tolerance revealed in (beta)arrestin-2 knock-out mice.
(J Neurosci, 2002-12-01)
Morphine induces antinociception by activating mu opioid receptors (muORs) in spinal
and supraspinal regions of the CNS. (Beta)arrestin-2 (beta)arr2), a G-protein-coupled
receptor-regulating protein, regulates the muOR in ...
Inner speech and bilingual autobiographical memory: a Polish-Danish cross-cultural study.
(Memory, 2002-01)
Thirty years after fleeing from Poland to Denmark, 20 immigrants were enlisted in
a study of bilingual autobiographical memory. Ten "early immigrators" averaged 24
years old at the time of immigration, and ten "late immigrators" ...
Production and recognition bias of stylistic sentences using a story reading task.
(J Psycholinguist Res, 2002-03)
Four experiments examined participants' ability to produce surface characteristics
of sentences using an on-line story reading task. Participants read a series of stories
in which either all, or the majority of sentences ...
BOLD signal compartmentalization based on the apparent diffusion coefficient.
(Magn Reson Imaging, 2002-09)
Functional MRI (fMRI) can detect blood oxygenation level dependent (BOLD) hemodynamic
responses secondary to neuronal activity. The most commonly used method for detecting
fMRI signals is the gradient-echo echo-planar imaging ...
A pathway in primate brain for internal monitoring of movements.
(Science, 2002-05-24)
It is essential to keep track of the movements we make, and one way to do that is
to monitor correlates, or corollary discharges, of neuronal movement commands. We
hypothesized that a previously identified pathway from brainstem ...
Effectiveness of mentoring programs for youth: a meta-analytic review.
(Am J Community Psychol, 2002-04)
We used meta-analysis to review 55 evaluations of the effects of mentoring programs
on youth. Overall, findings provide evidence of only a modest or small benefit of
program participation for the average youth. Program effects ...
A brief history of research synthesis.
(Eval Health Prof, 2002-03)
Science is supposed to be cumulative, but scientists only rarely cumulate evidence
scientifically. This means that users of research evidence have to cope with a plethora
of reports of individual studies with no systematic ...
